Children's progressive development orthotic system

摘要

A system of progressively-sized orthotic inserts is provided to allow increasing measured support that corresponds with the changes that occur in a child's arch as the foot develops. The orthotic insert system is designed to address the specific needs found in the foot for children of ages of about 2-8 years. Each of the plurality of inserts is designed to encompass two shoe sizes and vary in arch height relative to the insert length so that motion control and stabilization for the child's foot is provided. In addition, a contoured heel cup and rear foot post is provided to position the foot in a neutral position.

主权项

1. A method of supplying an orthotic system for children aged 3 to 9 years old, comprising the steps of: forming a plurality of progressively-sized individually molded inserts, the inserts having an arch height, a length and a thickness, the inserts configured to contact the plantar portion of a child's foot from the metatarsal heads, including supporting the plantar arch, and extending to include a contoured heel cup, the inserts further including a rear foot post, wherein the inserts are adapted to provide coverage of the plantar foot proximal to the metatarsal heads, the arch of the midfoot, and extend to the heel;
wherein the height (H) of the arch is proportional to the length (L) of each insert, wherein the proportionality of the arch height (H) to the insert length (L) of each insert is described by the equation H=0.425(+/−0.015)L−1.35(+/−0.05); and wherein each progressively-sized insert is configured for insertion into one of a plurality of progressively-sized child shoes, wherein the plurality of progressively-sized child shoes ranges in shoe sizes 7 to 13, and further wherein each progressively-sized child shoe is adapted to fit a child's foot as the child's foot progressively grows.
